Actually very similar - over 2k hours and kinda wondering why I even played it so much. Oh wait, i know - for years there's been always a party of friends who played or started playing Dota 2 and were constantly asking me to come and join. There was some fun, but it's impossible to threat the game seriously. Not when a random teammate can ruin the match for you. Or when you carry some useless troll, who does nothing but feed and spam in Russian some random nonsense - how many times I was wondering if I should not just let enemy team win so this guy doesn't get undeserved win? Geesh the more I think about it the better I feel for not playing anymore.Dota 2
As it was already said before, Dota 2 community is very toxic and once you spend a lot of time there, you become one of them. This hurts not only to personal well-being but to relationships with family and close friends. Fortunately, I've managed to quit it and I will never come back (I hope ).
The only thing I regret is wasted time. I have over 2,500 hours on my main account and there were a couple of others. Although I've made some money by selling items, it still feels bad, I could achieve something meaningful over this time.
Other than Dota 2 I guess i had to take some breaks from SC2. Either because I was becoming very angry with myself or something in balance was tilting me beyond acceptable limits. Few weeks or months and I would be back, mind you. But these breaks do help, even if they make your mechanics rusty, being able to distance yourself is important even if you're not aspiring pro or even GM player.
